Refinements made to MarkerNode memory use
Resolved in Pega Version 8.5
Significant memory usage can be observed when data join in strategies are missing the join conditions. E.g., when the primary source in the strategy can have up to 300 or even more propositions, the join without the join condition would perform a cartesian product with possibly up to 400 or even more records returned. This may cause performance degradation. To guard against this, an update has been made that seeks to prevent repetitive markers being accumulated under a MarkerNode while trying not to rely on any implementation of equality and hashCode for individual marker implementations.

Improved management for table pr_log_dataflow_events
Resolved in Pega Version 8.5
The Lifecycle event table was sometimes growing too large. This additional strain of database transaction volume caused poor performance on the Dataflow tier and lead to cluster instability and time-consuming cluster restarts. Due to problems in one of the Pulse tasks, the Pulse thread was not processing single case metrics properly and causing the unbounded queue for single case to grow. This has been addressed by switching to a fixed queue size, which is configurable with the DSS: dnode/single_case_queue_size. The default value of the DSS is 4000, and if changed a system restart is required. An error will be logged each 1000 queue misses, and metrics will be dropped if the queue is full. In addition, the Pulse task frequency has been improved and managed to prevent interference with other Pulse tasks and will be triggered only if a run is system-paused for a long interval. Rebalances now have a failsafe if something unexpected happens during the Pausing of the run, and If the cluster becomes unstable, the life cycle events logs may be disabled with dataflow/run/events/persist .

Properties persist after revision import
Resolved in Pega Version 8.5
When properties were added to a form, they sometimes disappeared after revision import even though the properties always remained visible in a strategy. Investigation showed that the Form changes made in a DD rule were not properly updated in the pyEditElement section. To correct this, logic has been added to handle the form changes in the DD in the following activities: Data-Rule-Summary.pyMergePropositions Data-Rule-Summary.pyRemoveDDRules Data-Rule-Summary.pyWithdrawDDChanges Data-Rule-Summary.pyRemoveRestoreDDRule

DataSet preview will use date instead of datetime
Resolved in Pega Version 8.5
While using a DataSet preview functionality, the date appeared as reduced by one day. This has been resolved by parsing date as 'date' instead of 'datetime' to avoid issues with timezone interactions.

Paging method updated for Select All in Broken Queue
Resolved in Pega Version 8.5
After clicking the 'Select All' box in Broken Queue In Admin Studio, scrolling up and down rapidly caused the checkboxes to be unselected. This was traced to the use of progressing paging in this scenario, and has been resolved by removing progressive paging and replacing it with the out of the box '1 of X' paging method.

REST parameters updated for SauceLabs compatibility
Resolved in Pega Version 8.5
After configuring a call to SauceLabs testing through Deployment manager, the REST call was timing out. Investigation traced the issue to SauceLabs changing its parameter name from "browser" to "browsername", and the Pega parameter names have now been updated to reflect that change.

Component rule check added to suppress unnecessary guardrail warnings
Resolved in Pega Version 8.5
After creating a component application using Configure > Application > Components, guardrail warnings were seen when saving the component. The component application allowed adding rulesets or other applications, but did not have all the tabs found in a normal application, so there was no option for adding the associated classes to define the UI class, Integration class and data class in the component application. As component is mostly a part of (or embedded inside) an application, this function was not given options to justify or suppress guardrail warnings like Rule-Application. To resolve this, a check has been added for component rule before generating guardrail warnings for Empty UI page, Empty Integration class, and Empty Data class.
